The photos taken with the 5D2 body and the 24-70 lens feel very fleshy, hazy, and look virtual. What’s going on?

The vignetting should not be obvious. You can determine whether it is a lens problem or a hood problem.

1. The method is to remove the hood and see if there are still dark corners. If the vignetting improves, it's because the lens hood is blocking light from the corners of the lens. Just replace it with the original lens hood.

2. You can also remove the hood and take photos of places with uniform brightness, such as the sky, walls, etc., and then compare the photos with Xiaobai's samples. If there are obvious dark corners, it is a lens problem.

24-105 and 24-70 have different uses.

1. In terms of focal length, as a camera head, 24-105 F4 is the golden focal length. 95% of photography content in daily life can be completed with 24-105. 24-70 is a classic focal length, which can probably complete 85% of daily photography. If you don’t want to change machines frequently.

2. The price of 24-70 F2.8 is a bit higher than that of 24-105, and the aperture is one stop larger. It has advantages in low light conditions, such as indoor light in a bar. It may be handheld with 1/15s F2.8 It is easier to ensure film quality than 1/8s F4.

3. For background blur, 24-70 is similar to 24-105, one has a larger aperture and the other has a longer focal length. If you use it well, you can get a hazy background.

4. In terms of picture quality, there is no problem after using it, all are red circle heads. Unless you shoot the same scene with a stand and then compare it carefully on a computer, it would be difficult to tell the difference between the two shots.

Hope you can find the answer
